A stormy pattern ahead for most of the Heartland; sharply colder air on-the-move

During an upcoming period of volatility, various parts of the country will endure extreme weather, including blizzard conditions, high winds, and lower temperatures.  Over the next 5 days, the primary storm track will extend northeastward from the Southwest. 

The leading storm system, already crossing the southern Plains, should reach the middle Atlantic Coast by Saturday night, with accumulating snow expected to be heaviest (locally 6 to 12 inches or more) in the Northeast.
